Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
Answer:
The rotation of the rectangle, of area 12 squared units, about y-axis produces a cylinder, with a volume of 48
cubic units.
Step-by-step explanation:
Rotation about x-axis or y-axis at an angle requires some general rules. When a 2D figure is rotated about a line a 3d figure would be produced. This can be done through a process called solid of revolution.
From the question, connecting the given coordinates produces a rectangle with a length of 4 units and width 3units.
Area of the rectangle = Length × width
= 4 × 3
= 12 square units
The required rule for rotation of a figure about y-axis is: (x, y) → (-y, x).
If the given rectangle is rotated about y-axis, a cylinder would be formed.
The volume of the cylinder = V = 
h
where: r = 4 units and h = 3 units.
V =
×
× 3
= 48
cubic units
Therefore, the rotation of the rectangle of area 12 squared units produces a cylinder with volume of 48
cubic units.
Answer:
Step-by-step explanation:
Alright, lets get started.
In the morning Cynthia completed the work = 
During her lunch break, she completed = 
So, she completed total of her work : 
So, we need to add these two fractions.
First making common denominator , so

So, adding = 
It means she had finished
fraction of het to do list. : Answer
